Control Center

This section describes known issues of the N1 Provisioning Server Control Center.

Administration Screen Timeout Issue

In certain cases, when you navigate from the Administration screen to the Editor screen and the session times out, you might not be able to log into the Control Center. Close the browser, open another browser, and log in again.

If you are in the Administration screen and the session times out, when you log in again, the window might display incorrectly. If this happens, close the browser and log in again.

To vary the session timeout, modify the timeout setting in web.xml in the /opt/terraspring/gw/war/WEB-INF directory. Look for the session-timeout tag. The value is specified in minutes. (4849661)

Find Farm Window Displays in Full After Timeout

If you press the Find button in the Find Farm dialog after the Find Farm session has timed out, the Find Farm window displays in full. Increase the timeout value. To do so, modify the timeout setting in the web.xml file in the /opt/terraspring/gw/war/WEB-INF directory. Look for the session-timeout tag. The value is specified in minutes. (4849673)

No Rollback After Farm Update Failure

When a farm update fails, changes do not always roll back to the last good state of the farm. The workaround for the problem is as follows:

1. To clear the error state, ping the farm using farm -pf farm-ID.

2. View the farm in the farm editor.

3. From the farm editor, select the latest farm update request from the Request History panel on the left. The correct farm information will display.

4. Choose File->Commit to submit the farm update again. A newly updated request is issued.

5. Unblock the new request. The correct farm information will display in the farm editor after the request is completed.

Display of Newly Created Items in List

When you create a new item such as an account, contract type, or articles, the newly created item will not be autoselected after creation. To view the newly created item, select it from the appropriate list. (4849691)

Do Not Bookmark Login Page

Do not bookmark any page except the welcome page. (4849693)

Allow Dialog Pages to Finish Downloading Information

In some dialog pages, for example, Select: Disk Image, the application needs to download information from the server. If you click any buttons on the page before that download is complete, a script error occurs. Wait until the page has finished downloading all information from the server before taking any actions. (4849697)

JavaScript Error When Configuring a Provisionable Server

While configuring a provisionable server, if you wait more than two hours on the dialog page before attempting to select an image for that server, you are taken to a new page to log in. After logging in, you will see a JavaScript^TM error. Close the dialog page and reopen it. (4849700)

Configuring I-Fabric Properties

Sometimes while configuring Infrastructure Fabric (I-Fabric) properties, if the newly created property name or property value contains a long string with special characters such as $, %, or #, the Commit Changes task will not work properly. Do not use special characters in I-Fabric properties. The maximum string length for the property name is 12 characters, and for the property value the limit is 30 characters. (4849701)

Unable to Submit I-Fabric Change

If a farm name is more than 25 characters long, the OK button disappears in the Change I-Fabric dialog for that farm. Ensure that the farm name does not exceed 25 characters. (4849706)

Snapshot Button Not Disabled for New Disk Created

When you create a new disk by flexing a server group, the snapshot button is not disabled as it should be. When you click that button, an error message appears. (4849721)

Default Gateway Value on Farm Summary Page

When a default gateway for devices on an external subnet has been configured to point to an external router, the farm summary page lists the default gateway as NONE. This behavior is caused by devices on an external subnet with no specified default gateway being automatically configured to use the external router. Ignore the NONE value on the display. The devices will function as expected. (4856847)

Deleting Snapshots or Images From the Control Center

When you delete snapshots and images from the Control Center, they are only marked as deleted. They are not yet deleted from the I-Fabric. Until you delete them from the I-Fabric, you will not be able to create snapshots and images with the same names as the ones marked as deleted.

To purge snapshots and images from the I-Fabric, issue the image -lR command from the control plane server to view a list of the images marked as deleted. Then issue the image -d command to delete them from the I-Fabric. See the image command man pages for details. (4856854)

Renaming a Farm

When you rename a farm using a farm name that already exists, a naming collision occurs. The farm details widget will show incorrect information about the farm although the information is not lost.

To resolve this, rename the farm again. From the File menu, choose Save As (or Rename) to save the farm under a new name. If this attempt is successful, the farm details will show the correct information. (4856858)

Setting a New Password

If you enter a value into the New Password and Reenter New Password fields and click the Reset button, the value in these two fields does not reset. To resolve this, remove the entered information from the New Password and Reenter Password fields and click the Reset button to reset the value. (4856860)

Pressing the Find an Image Button Causes an Error Message to Display

Duplicate names within the same account can cause unexpected behavior inside the Control Center and error messages to display. In most cases, the Control Center prevents you from creating duplicate names within the same account. However, sometimes the Control Center will allow you to create duplicate names, for example, while updating the software or application names.

Do not create duplicate names within the same account. Call your technical support representative if you inadvertently create a duplicate name within the same account.

BOM Does Not Show Backhaul Devices

The bill of materials (BOM) dialog only shows information about devices managed by the N1 Provisioning Server. Backhaul devices are considered nonmanaged devices, so the BOM dialog does not include information about backhaul devices. (4856865)

Multiple Displays of Operating Systems on the Find an Image Page

On the Find an Image page, the Operating Systems and Applications selection lists might show the same operating system or application multiple times if the same name has been used for operating systems and applications in multiple accounts. To retrieve the expected results while running a search, select all instances of the particular operating system and application in the list that you want to search for. (4856866)

Graphics Not Displayed Correctly After Reload Operation

Sometimes when you reload a current farm, the graphics in the navigation bar do not display correctly. Refresh the page. (4857740)

Control Center Client Software Requirements

The Control Center requires the Internet Explorer, version 5.5 or 6.0, web browser with a 128-bit security encryption. (4857757)

Monitoring Information Display for Farms

Monitoring information is not available for locked farms. Unlock the farm and refresh the monitoring page to view and edit the monitoring information. (4919192)

Control Center – IDB Image Synchronization

When you create an image from the Infrastructure Database (IDB), make sure that the image name is no longer than 32 characters. Otherwise, the synchronization of the image with the Control Center database will fail. (4919193)

Farm Naming Conventions

When you create or rename a farm using a name that already exists, a naming collision occurs. The farm will be temporarily named “New Farm” in the farm details widget to indicate that the farm is not properly saved. If you then decide to change the I-Fabric of this farm and no further error occurred, the farm will be saved as “new farm” with a space in the name. Spaces in farm names are not acceptable. Save the farm with a different name whenever a name collision occurs. (4919210)

Changing Server Group Names

When changing the name of a server group, the number of servers in the group must be 25 or less. If you have more than 25 servers in a group, remove servers from the group to reduce the number of servers to 25 or less, then add them back to the group after the name change process completes.
